# Patch does 4 things:

# - Always look for openjazz.000 in /usr/share/games/openjazz. Saves the user
#   from having to keep copies or symlinks of it in every game dir.

# - Writes config file to user's homedir, not current dir.

# - For .psm (music) files, if they're not found as "blah.psm", try the
#   all-uppercase "BLAH.PSM" instead. Saves the user having to rename
#   them (and keeps things consistent, EVERYTHING ALL CAPS). In case you're
#   wondering, the lowercase psm filenames are hardcoded inside the data
#   files from the DOS game, not the source.

# - Logs the full path & result of every attempted file open. I needed
#   this myself to understand WTF was going on, leaving it in case
#   users find it helpful.
